CONVEYING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 389,242, datedSeptember 11, 1888.

(No model.)

To all whom, it 721.0;1 concern:

Be it known that I, HENRY U. PALMER, a citizen of the United States,residing at Brooklyn, county of Kings, and State of New York, haveinvented certain new and useful Improvements in Conveying Apparatus,fully described and represented in thefollowing specification and theaccompanying drawings, forming a part of the same.

This invention relates to a conveying apparatus for use in coal-yards,warehouses, and similar places for conveying coal and similar substancesfrom one point to another and delivering them into any one of a seriesof bins.

In the accompanying drawings, Figure l is a side elevation of a numberof coal-bins provided with a conveying apparatus embodying the presentinvention. Fig. 2 is a sectional elevation of the same, takensubstantially on the line 2 of Fig. 1. Fig. 3 is an enlarged side viewof one of the supports upon which the conveyer travels. Fig. 4 is avertical section of the same, taken on the line 4. of Fig. 3.

Referring to said figures, it is to be understood that A represents anumber of elevated bins constructed and arranged in the ordinary mannerfor the reception of coal or similar substances. These bins are formedat their bottoms in the shape of hoppers, and are provided with chutesa, controlled by suitable gates, 12, through which the coal isdischarged either directly into wagons or into a hopper, c, mounted upona movable scale, B, by which it can be weighed and then discharged intothe wagons. The chutes u, are provided with the usual screens, (1, whichoperate to screen the dust out of the coal as it passes from the bins A.The dust thus ren1oved from the coal enters ehutesf and is discharged atany convenient point.

In filling the bins A the coal or other substance is discharged from thecars or boats into an elevated hopper, D, and from this hopper it passesthrough a suitable chute, 9, onto a conveyer consisting of an endlessbelt, 71, which passes around suitable pulleys, i, and is arrangeddirectly over the partition 7;, which separates the two rows of bins A.The belt h, forming the conveyer, is driven from any suitable source ofpower (not indicated) through a belt, Z, which passes around a pulleyupon the shaft of one of the pulleys i, or in any other suitable manner.

In those cases where the coal is discharged from cars by means of aconveying and elevating apparatus such as or similar to that shown in myprior application for Letters Patent filed December 9, 1887, Serial No.258,27 3, it may be delivered directly onto the belt h from theelevating apparatus instead of being delivered into the hopper D.

The belt h, forming the conveyer, is supported between the pulleys i bymeans of rolls m,arranged at suitable intervals. Some or all of theserolls arejournaled in tiltingbeariugs a, which are adjustable uponsupports N, so as to be capable of being adjusted from a horizontal toan inclined position in either direc tion. For the purpose of securingthe rolls a in any position to which they are adjusted the supports Nare provided with locking bolts 0, which pass through slots q, formed inthe bearings n and supports N, and are provided with nuts 8, by whichthey can be tightened, so as to hold the rolls and their bearings in anyposition to which they are adjusted.

The manner of using the apparatus thus constructed is as follows: \Vhenit is desired to fill any one of the bins A, the roll at which supportsthe conveying-belt h at a point near the middle of the bin will beadjusted from its horizontal position so that it will incline toward thebin which is to be filled at an angle of about forty-five degrees, asindicated in Figs. 1. and 2, thereby causing the conveyingbelt as itpasses over the roll to assume a corresponding inclination to thatpoint. The coal as it is delivered onto the conveying-belt will passforward on the belt over the rolls m which are arranged in a horizontalposition until it arrives at the roll which has been adjusted to theinclined position, as stated. As the coal upon the belt arrives at orabout at this point it will, owing to the inclination of the belt, slideoff laterally and pass into the bin which is to be filled, and so theoperation will continue.

hen one bin has been filled and it is desired to fill another, the rollwhich has been set at an incline will be returned to its horizontalposition and the corresponding rollover another bin will be adjusted toan inclined position, and the operation will be the same. By adjustingthe rolls m to a correspondinglyinclined position in the oppositedirection the bins upon the opposite side of the conveyingbelt may befilled in the same manner.

If preferred,the supports N,which carry the rolls m,n1ay be made movableinstead of being stationary, or the belt may be supported by a number ofrolls or which are not adj ustable,as described, there being providedone or more of the rolls m which are mounted upon movable supports N, sothat it or they can be moved from one position to anot-her,and thus bebroughtinto position to incline the belt over any bin that it is desiredto fill.

In those cases where the bins are arranged in a single row instead of ina double row, as shown, the conveyer may be located in any convenientposition over the bins, instead of being arranged over the partitionbetween the two adjacent rows of bins.

I am aware thatit has been proposed to construct a grain-conveyerconsisting of two horizontally-moving parallel belts which wereconnected by a strip of canvas which formed a trough-like apron betweenthe belts for 0011- taining the grain, and also that it has beenproposed to discharge the grain from the conveyer by means of narrowpulleys which were located at the point-of discharge and acted againstthe under side of the trough at its center and operated to reverse thetrough or turn it inside out, and thus cause the grain to fall oft atthe opposite sides, partly on one side and partly on the other, astructure of this description being shown in United States LettersPatent No. 97,070. The conveyer thus organized differs from mine inseveral important particulars. The reversal of the trough to dischargethe contents caused the contents to be discharged simultaneously uponboth sides of the conveyer,and thus rendered it impossible to utilizethe conveyer for filling two rows of bins arranged side by side, whereasin my organization, the belt being simply tilted or inclined in onedirection or the other, the contents are discharged wholly on one sideand the conveyer is available for filling two rows of bins arranged sideby side. the reversal of the trough made it necessary for the contentsin order to be discharged to pass up a steep incline to arrive inposition to slide off at the sides. This caused the contents toconstantly fall back and accumulate in the trough just in front of thepoint of disoharge,and this accumulation put great weight and strainupon the conveyer and made it hard to operate. In my organization bysimply tilting the belt this ditficulty is entirely avoided.

\Vhat I claim is 1. The combination, with the horizontallytravelingconveying-belt h, arranged above the bins to be filled, and a chute fordirecting the coal or other substance onto the belt, ofan inclinedsupporting-roll, m. extending across the width of the belt and adaptedto tilt or incline the belt at the point of discharge, sub stantially asdescribed.

2. The combination, with the horizontallytraveling conveying-belth,arranged above the bins to be filled, of a supporting roll or rolls,m, extending across the width of the belt and adjustable to incline ineither direction, and adapted to incline the belt to discharge the coalor other substance in either direction, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
